The worst of exJW reddit is as you say but the best is worth checking out. Perhaps it was the time when you checked in, but the moderators have attempted to highlight the more thoughtful posts and put less emphasis on memes and photos. One thing I have noticed is the number of well written posts by younger PIMOs or exJWs.
The reddit moderators do not intrude beyond reminding posters of the need to follow the rules. One of the difficulties I have with this forum is it does descend from time to time to a degree of ill-tempered posts decrying either the right or (more likely) the left with the level of debate down to who can make the most controversial statements about "some" exJWs. But I also acknowledge that this forum is a platform for some of the most compelling posts on moving on from JW organization I have ever read.
